5. Konfigurazioa eta instalazioa
Instalazio egokia ezinbestekoa da errendimendu eta segurtasun optimoa lortzeko. Urrats baten inguruan ziur ez bazaude, kontsultatu instalatzaile profesional bati.
5.1 Muntaketa Ampbiziagoa
Choose a mounting location that is dry, well-ventilated, and secure. Ensure sufficient space around the amplifier for air circulation. Use the provided mounting hardware to firmly secure the amplifier to a solid surface in the vehicle.

5.2 Kableatutako konexioak
Refer to the diagram below for connection points. Always use appropriate gauge wiring.
5.2. irudia: Amaituview of amplifier connections and controls.
- Energia konexioa (+24V): Connect a fused 24V power cable directly from the vehicle's battery. Ensure the fuse is located close to the battery.
- Lurreko konexioa (GND): Connect a short, heavy-gauge cable from the ampkonektatu bizigarriaren GND terminala ibilgailuaren xasiseko metalezko gainazal garbi eta margotu gabe batera.
- Urruneko piztea (REM): If using low-level inputs, connect this to the remote output of your head unit. If using high-level inputs with Auto-Turn-On, this connection may not be necessary.
- Bozgorailuaren irteerak: Connect your speakers to the FRONT and REAR output terminals. Observe correct polarity (+/-). For bridged mode, refer to the specific bridging instructions.
- Sarrerako konexioak:
- Goi-mailako sarrera: Connect the speaker outputs from your head unit directly to the amplifier's high-level input terminals. This is ideal for factory radios without RCA outputs.
- Maila baxuko sarrera (RCA): Zure unitate nagusiak RCA aurre-irteerak baditu, konektatu itzazu amplifier-aren RCA sarrera-konektoreak.
5.3 Auto-Turn-On Function
The AT401 features an Auto-Turn-On function for high-level inputs. This allows the amplifier to turn on automatically when it detects an audio signal from the head unit, eliminating the need for a separate remote turn-on wire. Ensure the switch is set to the appropriate mode (DC or VOX) for this function.

6. Funtzionamendu-argibideak
Once installed, the AT401 amplifier offers various adjustments to fine-tune your audio system.
6.1 Gain (SENS) Adjustment
The gain control (SENS) matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum. Gradually increase the head unit volume until distortion is heard, then back off slightly. Then, slowly increase the amplifier's gain until the desired volume is achieved without distortion.
6.2 Crossover (X-OVER) Settings
The AT401 features integrated 12 dB/octave electronic crossovers, adjustable from 40 to 400 Hz. These allow you to filter specific frequency ranges to your speakers.
Image 6.1: Adjustment options for crossovers and input sensitivity.
- HPF (Pasa handiko iragazkia): Maiztasunak onartzen ditu goian the set point to pass through. Use for full-range speakers to prevent low bass distortion.
- LPF (Pase Baxuko Iragazkia): Maiztasunak onartzen ditu behean the set point to pass through. Use for subwoofers.
- OSOA: Disables the crossover, allowing all frequencies to pass.
Adjust the FREQ knob to select the desired crossover frequency for each channel pair (FRONT/REAR).
7. Mantentzea
- Mantendu ampGarbitu lifatzailea oihal leun eta lehor batekin. Ez erabili produktu kimiko gogorrik edo garbitzaile urratzailerik.
- Ensure that the heat sink fins are free from dust and debris to maintain proper cooling.
- Aldian-aldian egiaztatu kableatu guztien konexioak estutasuna eta korrosioa duten ikusteko.
